Subject: [Qemu-devel] Debugging registers DR0, DR7 don't work
Date: Wed, 09 Feb 2005 22:50:09 +0100 [thread overview]
Message-ID: <420A8591.4090208@email.it> (raw)
I'm Paolo Minazzi and I am a new user of QEMU.
I use it to learn protected mode programming in asm.
QEMU is very useful as I can avoid to reset continuosly my PC.
Nevertheless I have a problem.
I have tried to write an asm program to try dr0 and dr7 debugging register.
I have found that this register don' work and I cannot receive the
excepction 1.
My program instead works fine in a real DOS system.
Does someone indicate me how to enable debugging register with QEMU ?
Thanks in advance
Paolo Minazzi
